B.

C.
between 10 and 12 hours​ (24 to 36​ cars)
D.

Answer 1

a. Outliers: (2, 39), (10, 3), (5, 27).

b. Clusters: A and B.
- A: between 3 and 6 hours (5 to 13 cars)
- B: between 8 and 11 hours (26 to 34 cars)

c. Gap: there is a gap roughly between about 6 and 8 hours (and the corresponding car counts between the two clusters). A likely cause is no data were collected at those times (or the lot was closed or otherwise unavailable during that period), so no points appear there.
